I've been assuming that this bit about "eye flickers" is boyd's way of describing for a general audience the phenomenon of optical saccades, which are automatic and very fast eyeball twitches which allow the brain to gather enough information to construct a visual scene through an eyeball with a (usually) very narrow area of focus.
I'm not sure how that affects shape-from-shading, though, because saccades are movements of the eyeballs only, not of the head. Saccades therefore don't affect angles of reflection or refraction, which would seem to make it impossible for them to change the shading of a given scene.
- acqq 13y agoThe fact is that for VR to be accurate, we'd have to do very fast tracking of the eye movement and even the change of the focus of the eye. Both are certainly used by our brains to unconsciously calculate the distance of an object. Both can happen independently of our head movements. I can easily recognize that such adjustments of the picture aren't present in immersive 3D projections. Add to that that we males are much less aware of the incorrectness of the shades, it's easy for me to imagine that women have bigger problems under given conditions.
